[HELP] Please help me understand this error
Code:
[COLOR=#000000]System.NullReferenceExeption: Object reference no set to an instance of an object. at COServerProject.Client.GetPacket(Byte[] data) in c:\***\client.cs:line 7785[/COLOR]
I need specifics. All my reading has told me is that this error occurs when a string is not null. Knowing the quick fix would be nice, but understanding the error would pwn.
Thanks in advance for your helpful replies.

He means he has to see the code (the function) that is causing the errors, otherwise he can't possibly guess what needs to be fixed.

Crap, sorry dumb moment. Here you are: (Client.cs statement)
Code:
if (Control <= 16 && Control >= 10)
{
string TheEquip = "";
if (Control == 10)
TheEquip = MyChar.Equips[1];
if (Control == 11)
TheEquip = MyChar.Equips[2];
if (Control == 12)
TheEquip = MyChar.Equips[3];
if (Control == 13)
TheEquip = MyChar.Equips[4];
if (Control == 14)
TheEquip = MyChar.Equips[6];
if (Control == 15)
TheEquip = MyChar.Equips[8];
if (Control == 16)
TheEquip = MyChar.Equips[5];
byte Pos = 0;
if (Control == 10)
Pos = 1;
if (Control == 11)
Pos = 2;
if (Control == 12)
Pos = 3;
if (Control == 13)
Pos = 4;
if (Control == 14)
Pos = 6;
if (Control == 15)
Pos = 8;
if (Control == 16)
Pos = 5;
string[] Splitter = TheEquip.Split('-');
uint ItemId = uint.Parse(Splitter[0]);
if (!Other.Upgradable(ItemId))
return;
byte RequiredMets = 0;
if (Other.ItemInfo(ItemId)[3] < 120)
{
RequiredMets = (byte)(Other.ItemInfo(ItemId)[3] / 10);
if (RequiredMets == 0)
RequiredMets = 1;
}
if (RequiredMets != 0)
{
if (Other.ItemQuality(ItemId) < 7)
RequiredMets = 2;
if (Other.ItemQuality(ItemId) == 7)
RequiredMets = (byte)(2 + RequiredMets / 5);
if (Other.ItemQuality(ItemId) == 8)
RequiredMets = (byte)(RequiredMets * 2.6);
if (Other.ItemQuality(ItemId) == 9)
RequiredMets = (byte)(RequiredMets * 3.1);
}
Here is the specific line(7785):
Code:
string[] Splitter = TheEquip.Split('-');
And here is the Database.cs statement:
Code:
public static byte Authenticate(string UserName, string Password)
{
try
{
MySqlDataAdapter DataAdapter = new MySqlDataAdapter("SELECT * FROM `Accounts` WHERE `AccountID` = '" + UserName + "'", Connection);
DataSet DSet = new DataSet();
DataAdapter.Fill(DSet, "Account");
if (DSet != null && DSet.Tables["Account"].Rows.Count > 0)
//if (DSet.Tables["Account"].Rows.Count > 0)
{
DataRow DR = DSet.Tables["Account"].Rows[0];
string Pass = (string)DR["Password"];
if (Pass == Password || Pass == "")
{
if (Pass == "")
{
MySqlCommand Command = new MySqlCommand("UPDATE `Accounts` SET `Password` = '" + Password + "' WHERE `AccountID` = '" + UserName + "'", Connection);
Command.ExecuteNonQuery();
}
uint LogonCount = (uint)DR["LogonCount"];
LogonCount++;
MySqlCommand Comm = new MySqlCommand("UPDATE `Accounts` SET `LogonCount` = " + LogonCount + " WHERE `AccountID` = '" + UserName + "'", Connection);
Comm.ExecuteNonQuery();
return Convert.ToByte((uint)DR["LogonType"]);
}
else
return 0;
}
else
return 0;
}
catch (Exception Exc) { General.WriteLine(Exc.ToString()); return 0; }
}
and line 1709:
Code:
DataSet DSet = new DataSet();

I appreciate you taking the time to look this over, but what does the indent have to do with the error I'm receiving.

The string "TheEquip" is null, and it's trying to split it.
